Abstract
The invention discloses a preparation method of thermal-insulation elastic exterior wall putty. The elastic putty consists of the following components in parts by weight: 14-16 parts of white cement, 6-8 parts of fly ash, 12-14 parts of ash calcium powder, 20-24 parts of calcium carbonate powder, 11-15 parts of hollow microsphere, 2-3 parts of cellulose ether, 0.8-1.2 parts of lignocellulose, 0.2-0.4 part of starch ether and 13-17 parts of pure acrylic emulsion. The exterior wall putty is excellent in thermal-insulation performance, and can maintain conventional performance of the putty.
Description
Technical field
The present invention relates to building material technical field, relate in particular to a kind of insulated elastic exterior wall putty.
Background technology
Current, along with social progress and rapid economic development, building trade gets prosperous with every passing day, and putty for building also grows with each passing day as the use of one of material of construction.Putty is as body of wall protective layer alignment material; should have suitable cohesive strength, good anti-cracking performance, water tolerance, permeability resistance and permeability with outer wall heat insulating system; also should have the heat insulation and heat control performance in addition, in order to reduce the generation that temperature becomes the crack, and improve indoor thermal environment.At present, the building energy consumption of China accounts for about 35% of social total energy consumption, and building energy conservation has been put into one of country's ten large energy conservation projects.In order to realize the target of building energy conservation 50% and 65%, to new building and existing building prevalence " external wall insulation project technology ", emphasis is carried out EPS/XPS plate thin plastering exterior wall heat-insulation system and PS particle slurry external thermal insulation system.Through facts have proved in the past few years because above-mentioned heat-insulation system exists that seam is many, the material internal stress greatly, the deflection that causes of poor dimensional stability, thermal stresses is large, therefore, very easily causes thermal insulation dehiscence, then cause protective layer and crackle occurs.And the performance of putty has played keying action to the performance of body of wall.Flexible break resistant putty performance requriements according to regulation among the JG158-2004 " glue powder polyphenyl granule exterior wall outer heat preservation system "; wherein to reach putty membrane curved be qualified around diameter 50mm rod flawless to snappiness; and traditional powdery putty is difficult to reach this requirement; because only have when the volume of latex powder reaches 13%; the snappiness of putty could satisfy the flawless regulation around diameter 〉=50mm; after powdery putty reaches flexible standard; the putty viscosity of making is large; cause difficulty to construction; and this class powdery putty cost performance is also inadvisable; these factors have all caused traditional powdery putty to be not easy to reach flexible standard; cause body of wall protective layer cracking, so that wall insulation performance reduces.How to be prepared into a kind ofly have suitable bonding strength, the excellent elasticity of covering crackle, good water tolerance and permeability resistance, preferably outside the permeability, also have simultaneously phase-changing and temperature-regulating, temperature control and incubation and thermal insulation function concurrently, with exterior wall heat-preserving system the paste phase-change energy-storing heat preservation heat insulating elastic putty of good consistency, matching and synergetic being arranged, then is the vital task that the current urgent need of the art solves.
